A preparation process of super large grinding wheel reinforced glass fiber mesh

Abstract

The invention relates to a manufacture technique for a reinforced glass fiber mesh of a super-large grinding wheel. The manufacture technique comprise the following steps: (1) soaking treatment is performed; (2), a glass fiber mesh cloth is woven; (3), a binding agent is prepared; (4), the glass fiber mesh obtained in the step (2) is uniformly soaked in the binding agent obtained in the step (3); (5),the glass fiber mesh cloth soaked with the binding agent is placed in a drying box for drying treatment, and the dried glass fiber mesh cloth for the grinding wheel is heated at 120-140 DEG C; and finally, the glass fiber mesh cloth subjected to heating treatment is cut into pieces so as to obtain the reinforced glass fiber mesh for the super-large grinding wheel. The manufacture technique has the advantages that good color fastness can be endowed to yarns, so that glass fiber yarns have excellent textile performance; the abrasion of raw silk is small during a textile process; and furthermore, through improvement on the binding agent, the binding effect and the strength of the grinding wheel mesh can be improved, so that the abrasion-resistance of the grinding wheel is improved, and the service life of the grinding wheel is prolonged.

Description

technical field [0001] The invention belongs to the technical field of grinding wheel mesh preparation, in particular to a preparation process of a super-large grinding wheel reinforced glass fiber mesh. Background technique [0002] The grinding wheel mesh is the skeleton of the resin grinding wheel, which plays a particularly important role in the strength of the entire grinding wheel and directly determines the quality of the grinding wheel. The general production process of grinding wheel mesh is as follows: wire drawing forming→glass fiber filament impregnation treatment→weaving glass fiber mesh cloth→glass fiber mesh cloth impregnated with adhesive→drying and slicing. [0003] Glass fiber has been used as a grinding wheel reinforcement material in China for many years. Glass fiber is brittle without surface treatment and cannot be applied. Therefore, the surface of glass fiber needs to be coated with a special surface treatment agent, that is, a sizing agent, to reali...

Problems solved by technology

The sizing agent has low viscosity, good fluidity and is easy to recycle, does not produce sludge, and the reclaimed sizing agent and waste water can be recycled without causing environmental pollution. Relatively poor firmness

The preparation method is to add alcohol to the mixer, add thermoplastic phenolic resin while stirring, and stir for 3-4 hours. After the phenolic resin block is completely dissolved, add thermosetting phenolic resin liquid containing coupling agent, plasticizer and alcohol-containing Toughening agent, stir for 3-4 hours, add curing agent, and continue stirring for 4-6 hours to obtain the adhesive; but the adhesive formula of the grinding wheel mesh is very simple, resulting in the combination of the mesh, sand and resin in the grinding wheel The force is weak and the combination is not tight, resulting in non-wearing of the grinding wheel and low service life
